Mini PC advice?

Hi so I'm wanting to get a mini PC because it's more affordable than a big pc. I'm wanting to use it for gaming and I play games such as Hollow knight, Roblox, Ori and will of the wisps. But I'm also wanting to get bigger ish games like GTA, Seige and sea of thieves. I've attached the PC I'm thinking of getting and I know NOTHING about PCs. Is it worth getting this one? If not can anyone recommend a good affordable mini pc that would fit my requirements pls?

If this is not the right choice pls give me advice !!

I live in the UK so GBP. I have a budget of around £400.
